RICHARD J. GATLING, OF ST. LOUIS, MISSOURI.

MOTOR PLOW.

SPECIFICATION forming part of Letters Patent No. 695,808, dated April 1, 1902.

Application filed July 18,1901. Serial No. 68,712. (No model.)

To (tZZ whom it may concern.-

Be it known that I, RICHARD J. GATLING, a citizen of the United States, residing in the city of St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Motor-Flows, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to that class of plows that are operated by a self-carried motor, an illustration of which is to be found in Letters Patent of the United States granted to me July 24 1900, No. 654,243.

The principal object of this invention is to provide means whereby the plow-carrier and the individual plows arranged in gang may be adjusted at the will of the operator to determine the width of ground overturned, the width of the furrows cut by the individual plows, and the depth of the furrows made in the practical use of. the implement.

The invention consists in features of novelty hereinafter fully described, and pointed out in the claims.

Figure I is a top or plan view showing my improved plow. Fig. 11 is a side elevation. Fig. III is an enlarged detail end View of the disk-plow carrier. Fig. 1V is an enlarged detail rear View of a fragment of the plow-carrier and one of the disk plows." Fig. V is an enlarged perspective rear view of the plowcarrier and the parts by which said carrier is connected to the frame of the plow. Fig. VI is an enlarged cross-sectional view taken on the line V1 V1, Fig. V, showing one of the disk plows in side view. Fig. VII is a detail rear view of a fragment of the forward end of the disk-plow carrier.

1 designates the mainor traction wheels of the plow, in which the axle 2 is journaled.

3 designates the forward or steering wheels, that are operated by throw-rods 1, connected to a hand-wheel 5, through means of which the steering-wheels are manipulated by the driver, who occupies the seat 6, mounted on the frame of the plow.

7 designates the frame, that is connected to the axle of the steering-wheels at its forward end and is mounted at its rear end on the axle 2. The plow is driven by a motor 8 of any suitable description. I prefer to employ a 17 designates a cross-bar attached to the 1 frame 7 at a position forward of the tractionwheels 1 and having its ends projecting beyond the rims of said traction-wheels. The cross-bar is connected to the frame 7 by forwardly-extending braces 18.

19 designates a carrier-beam, preferably of T-plate form, positioned in the rear of the traction-wheels 1 and at an angle to the axle 2, as clearly seen in Fig. I, so that one end travels in advance of the other end. The forward end of the carrier 19 is joined to the cross-bar 17 by a connecting-rod 20, provided with a series of apertures 21, that receive a bolt 22, by which the connecting-rod is adjustably held to the cross-bar 17. (See Fig. I.) The rear end of the connecting-rod 20 is mounted in a slotted swivel-bolt 23, loosely seated in a pair of ears 24, that project forwardly from the front face of the carrier 19, near the lower edge thereof. The rear end of the carrier 19 is joined to the cross-bar 17 by a connecting-rod 25, provided with a series of apertures 26, that receive the bolt 27, by which the connecting -rod, and consequently the rear end of the carrier, is. adjustably connected to the cross-bar 17. The rear end of the connecting-rod 25 is mounted in a slotted swivel-bolt 28, loosely seated in a pair of ears 29, projecting forwardly from the carrier 19, near the lower edge thereof.

30 designates a pair of stay-rods that connect the carrier 19 to the frame 7. The rear ends of these rods 30 are pivotally mounted in slotted swivel-bolts 31, seated in cars 32, that project forwardly from the carrier 19 at its upper edge. The forward ends of the rods 30 are screw-threaded and pass loosely through eyes 33, mounted on the rear end of the frame 7. On the threaded forward ends of the rods are nuts 3e and at opposite suspended from the forward ends thereof, as

- naled in hangers 51.

sides of the eyes, the said nuts being preferably spaced a sufficient distance apart to permit of play of the rods 30 in the eyes 33 and allow a limited endwise movement of said rods consequent upon movement of the carrier 19.

36 designates lift-beams pivotally connected to standards 37, carried by the frame 7, and which extend both forwardly and rearwardly of said standards. The rear ends of the lift-beams 36 are joined to the carrier 19 by links 38, the means of attachment between the upper ends of the links and the lift-beams being preferably ball-and-socket couplings 39, thereby allowing movement of the parts in all directions. The lower ends of the links are pivotally connected to knuckles 40, that are in turn pivotally joined to ears 41, surmounting the carrier 19, the arrangement or connection being such that free movement of the carrier with respect to the links 38 is permitted.

42 designates weights removably suspended from the lift-beams 36. These weights are designed for service in holding the carrier 19 depressed in the operation of the plow and when so used are suspended from the rear ends of the lift-beams, as seen in full lines, Fig. II, whereas when the plow is not in ser- Vice but is being transported the weights are removed from the rear ends of the beams and illustrated in dotted lines in Fig. II, where they serve to support the carrier 19 and the plows aflixed thereto. To provide for the operation of the lift-beams 36 to raise and lower the carrier 19, I employ cables 43, to which the forward ends of the beams are connected by clips 44.' These cables pass over and under sheaves 45 and 46. (See Figs. I and II.) The cables 43 may be shifted on the sheaves 45 and 46 in any desirable manner, either by manual power or by power communicated from the motor 8, and when the cables are so shifted the beams 36 may be lowered or raised to the desired extent. In Fig. I, I have shown the sheaves 45 of each cable 43 mounted on shaft 47, that is equipped with a ratchet 48 and designed to receive a crank whereby the sheaves may be turned to shift the cables.

49 designates a flexible stay, preferably of wire rope, that is connected to the frame 7 of the plow forward of the axle 2 and to the rear end of the carrier 19. This stay is designed for service in preventing endwise movement of the carrier 19 under the strain incurred in the operation of the plow.

I now come to the description of the disk plows and the-means by which they are adjustably connected to the carrier 19.

50 designates the disk plows or soil-working' members, the spindles of which are jour- Each of the hangers 51 is connected to the carrier 19 by a pivot-bolt 52, that passes through one of the perforations 19 in said carrier, the said perforations being located on a line below the center of the carrier, as seen in Fig. V. The upper end of each hanger 51 is provided with a lug 53.

54 designates a slide-bar loosely positioned beneath the flange 19 of the carrier 19 and containing a series of notches 55, adapted to receive the lugs 53 on the hanger 51. The slide-bar 54 is sustained by supporting-bolts 57, that pass through slots 56, contained by said bar. For the purpose of adjusting the slide-bar 54 I provide a screw-threaded rod 58, having one end held between ears 19, projecting from the carrier 19, and having its opposite end screw-threaded and seated in cars 54, carried by the slide-rod. -On the rod 58 between the ears 54 is an adjustmentnut 59.

In some instances, particularly in tough soils, the strain exerted against the carrier 19 by the gang of plows attached thereto may, it is obvious, have a tendency to force said carrier endwise in the direction opposite to that in which the soil is overturned. In order to counteract such tendency, I have provided means carried by the carrier at the front side thereof that will serve as retainers and offset the endwise movement of the carrier.

60 designates brackets fixed to the carrier 19, and journaled in these brackets are members 61, that may be and are preferably plowdisks, although wheels may be used in lieu of said disks, as indicated by dotted lines, Fig. I. The restraining members 61 are positioned in reverse direction to the position of the disk plows 50 and are preferably set at an incline to the c'arrier19, so that they will turn in or on the ground and exert an endwise pull on the carrierin a direction opposite to that exerted by the plow. I

In the practical use of this plow in tilling the soil the disk plows, with the carrier 19, are first lowered to the ground by manipulating the cables 43, so that the rear ends of the lift-beams 38 will be lowered and the disk plows caused to descend to the ground. The weights 42 being then suspended from the rear ends of the lift-beams, the implement is ready for service, and upon the motor 8 being put in operation the implement is selfpropelled over the ground to be plowed. Where it is desired to cause the plow to overturn the least amount of ground at one operation, owing to the nature of the soil being tough or difficult of working, the carrier 19 is set at the least possible angle relative to the path of the implement, being adjusted to said position by setting the bolts 22 and 27 in the apertures 21 and 26 of the connectingrods 20 and 25 in such positions that the desired angle of the carrier 19 will be obtained. In looser soils the bolts 22 and 27 maybe adjusted into varying positions in the connecting-rods, so that the carrier will be moved into greater angle with reference to the path of travel, thereby providing for the overturning of agreaterwidth of ground at a single operation, as will be obvious. When the adjustceases ment of the connecting-rods and is altered and it is desired to maintain the carrier 19 in the same relative position as before, the stay-rods are adjusted forwardly or rearwardly by manipulating the nuts 34 and 35 thereon. WVhen itis desired to effect a deeper cut of the plows into the ground, the carrier 19 is tilted by manipulating the connecting-rods 2O 25 and stay-rods 30 so that the lower edge of the carrier 19 projects in advance of the upper edge thereof, and the plows are thrown downwardly deeper into the ground, whereas when a lesser cut is to be made the rods 20, 25, and 30 are adjusted to place the upper edge of the carrier in ad- 'vance of the lower edge, thereby raising the plows, as illustrated in Fig. III.

In different soils it is desirable to place the disk plows at Varying angles, so that the amount of cut made by the plows may be regulated according to the nature of the soil. The plows are therefore so arranged that they may be shifted in unison to change their positions,the shifting being accomplished by. the adjustment of the slide-bar 54. On manipulation of the adjustment-nut 59 on the bolt 58 the upper ends of the plow-carrying hangers 51 are swung in either direction desired and the plows carried therewith by reason of the engagement of the lugs 53 in the notches 55 of the slide-bar. The variation in the positions of the plows is illustrated by full and dotted lines, Fig. IV.
